    I don't want to be rude but I just want to say for the thread that this system is complete overkill for general busking and only applicable if noise restrictions aren't in place where you are and your free to perform for a reasonably sized audience. Better for a group but a group will need a decent space to perform in.

    If noise restrictions are in place then a Roland AC-33 is more than loud enough to get you into trouble all on its own. Currently I'm plugging an ISK CM-60 battery powered condenser microphone into my AC-33 as a 1 microphone solution for voice ,ukulele and foot-tap. It works surprisingly well.

    I may replace the AC-33 at some point with a Behringer MPA40BT to get an 8" speaker instead of the 2 small speakers in the AC-33. The power of the MPA40BT will be complete overkill but it will be just about getting a clearer sound from the bigger speaker.

    You really don't need to be that loud to busk and being too loud is a hinderance rather than a benefit.
    Ric has done an amazing job over the past 10 years with this thread detailing an awful lot of "different" equipment, guess you didn't read all of that. Ric does not busk, he actually plays gigs for an audience, guess you didn't read that either. Guess you just want to point out how good your gear was. That's nice because it adds to the wealth of knowledge that has been assembled here but don't say his "system is complete overkill" because it is not. His intended purposes are much different then yours, if you had taken the time to read this thread you would have figured that out.

I like the sound, portability, size and weight of this system. Setup and teardown time are greatly reduced. Ric
    Thanks for the reply Ric.

    I myself try to find equipment that is powered by DC, converted from AC at the mains.

    This makes battery-powered use easier. Yes a 50 lb car battery is a PITA to haul around. I've found lithium-ion packs to have higher energy density than both SLA and NiMh and NiCd batteries, while also being much lower weight than a car battery.

    I have some 9v-AC and 18v-AC tube amps and tube preamps I'd love to be able to run on battery power, but would rather not use a sine-wave inverter...so instead, I've 'suffered' with solid-state based equipment that can do 9v-DC or 12v-DC at the power input jack.

    I've not been doing any performances myself, nor been responsible for the sound equipment for a while, so until I am looking at that again, will not be buying any equipment, but your thread here, with the carefully and thoughtfully discussed equipment options, will be a very useful resource for me when I am ready.

    I've read through the thread over the years and I qualified my post.
    Most people who want battery powered amplification are busking and I've seen people out busking with externally powered PA systems/amps that are complete overkill.
    There is a movement/attitude gaining ground that buskers should only be allowed to busk un-amplified and this is gaining strength because most buskers ARE too loud and despite numerous requests to keep the volume down they continue to be too loud.
    I do wish to be able to continue to busk amplified at a suitable/moderate volume so I'm addressing the issue.

    If Ric is playing gigs where the volume is acceptable/needed then fine. I said that. If your looking for busking amplification then I'm honestly saying that the 20watt (on battery) Roland AC-33 is loud enough to generate noise complaints all on its own and you don't need more power.

    We have cities here that have noise ordinances, where amplification does not work. We also have beach communities where loud motorcycles and cars are also passing by and you will not be heard without amplification. I perform at large wedding receptions and events where you would have to run a couple hundred feet of 10 gauge extension cords to power the amplification. I've done that in the past. I do occasionally busk, but not often. Out here farmers markets, street faires and art walks are almost always amplified. That's also at the request of the organizers and businesses to attract customers. We don't face some of the same issues as you do, anthonyg, because you have to be good enough to be allowed to busk here. If you are not sponsored by businesses and local government, you cannot legally busk acoustically or amplified. Kokua goes a long way in community inclusiveness. I own and use a Roland AC-33 and have several extra battery packs for it. It does not have the superior sound quality of the Bose S1 Pro at any volume, but I can run it for days on replaceable batteries and use it's internal looper, effects and feedback suppression. Horses for courses. Ric

    I've had a couple of examples in the last couple of days about just how hard it is for a performer to judge the correct volume needed.

    I run my 20 watt on battery Roland AC-33 at no more than half volume (the MASTER indicator straight up (at 12 o'clock)) and the channel Volume (microphone preamp) set at just the start of the "microphone" section. Well bellow the amps maximum volume potential. When I play I don't hear my voice at all (seriously, I don't hear my voice through the AC-33) and I only just hear the ukulele through the amp as a form of thickening my sound. Sometimes I tap the microphone just to make sure its on.

    I still got 2 comments on volume on 2 separate days. 1 was from a friend that said I was rather loud. I wasn't quite sure about it as its the usual situation between guys where he could have been having a lend of me. The day after a lady complained that I was too loud as well. She may have been rather sensitive but I turned the volume down anyway.

    When I play on stages with sound guys running the show I don't hear much either if there is no foldback and to be honest I tell them to turn the foldback down so I often don't hear much volume from the main speakers.

    The moral of the story is that you need FAR less volume than you think you do as the performer and if the volume sounds OK to you when you perform then its FAR too loud for the audience. That and an AC-33 is way loud enough for busking. I may get myself a bigger unit with an 8" speaker for a better sound but I will have to be very careful with the volume.
